IPC: A47J31/42
Filed: 1995-05-24
Abstract: The grinding unit comprises a grinding rotor unit, incorpo-rating a inlet screw member, a conical grinding tool member, a delivery dish member and a gear unit. A dog clutch is operation-ally inserted between the delivery dish member and the gear unit. A safety clutch is operationally inserted between delivery dish member and grinding tool which limits the torque to be transmitted. The safety clutch is provided with ball members lo-cated in axially running bores of the delivery dish member and being axially displaceable in these bores. The ball members are forced against the front face of the grinding tool and partially engage apertures provided therein under the influence of spring members assigned to each ball member. The delivery dish member is provided at its surface which faces the grinding tool member with a metallic disc member in which are located the mouths of axial bores containing the spring pressure loaded ball members.          The dog clutch comprises a plurality of elastic dampening mem-bers inserted between the claw members of the dog clutch.

Title: Fugitive colour fire retardant composition for aerial application
Inventor: CROUCH ROBERT L
IPC: A62D1/00
Filed: 1995-07-18
Abstract: In a fugitive colour fire retardant composition, the colourant initially colours the composition to a hue which contrasts with the hue of ground vegetation. A non-fugitive component is included in the colourant, in an amount which is sufficient to provide improved aerial visibility when the composition is first aerially applied to the vegetation. However, the amount of non-fugitive pigment is less than an amount which would prevent the composition from fading after application to an acceptable hue.

Patent CA-2168717-A1 (CA)
Title: Variable security level encryption
Inventor: ALANARA SEPPO
IPC: H04L9/06
Filed: 1996-02-02
Abstract: A method and apparatus for digital cellular telephone encryption includes a switch when a choice between compatibility security and a higher security is required.      Plaintext is converted into ciphertext using a three-stage transformation process. In a first stage, the plaintext is transformed using a secret key to control encrypting by an invertible transformation process. In a second stage, the output of the first stage is transformed by an involutory transformation, which is unkeyed when the compatibility switch is in a compatibility setting and keyed when the compatibility switch is in a secure setting. In a third stage, the output of the second stage is transformed by the inverse of the transformation performed in the first stage. The compatibility switch is used to toggle between compatibility with a less secure encryption standard and a key-based secure encryption.

Title: Pill crushing syringe with plug to impede crushed pill particles from prematurely entering the catheter
Inventor: KLEARMAN JEFFREY D
IPC: A61M5/31
Filed: 1994-12-14
Abstract: A pill crushing syringe (20) is disclosed which includes a barrel (22) and a plunger (24), with abraded surfaces (32, 44) on each so that a pill placed in the barrel (22) is crushed as the plunger (24) advances within the barrel (22).  The barrel (22) has an aperture (34) located near the closed end (30) with a catheter (26) connected around and extending from the aperture (34). The plunger (24) has a sealing gland (42) to provide an airtight seal with the barrel (22) so that liquid can be drawn into the barrel (22) through the aperture (34) by withdrawing the plunger (24) from the barrel (22) to thereby suspend the crushed pill in the liquid, and the suspension may be flushed from the barrel (22) by thereafter advancing the plunger (24) into the barrel (22). In an alternative embodiment a bi-level barrel (100) has an aperture in spaced relation to the closed end forming a pocket (116) wherein the crushed pill ingredients accumulate. The pocket (116) at the closed end (112) and the separation between the aperture and the barrel closed end (112) helps prevent the medication from escaping the barrel (100) via the side mounted catheter (104) prior to aspiration.  In still other embodiments, the syringe has a side entry plunger (146) or two opposing plungers (166). In a further alternative embodiment the aperture (212) extends through the otherwise closed second barrel end (208) and the catheter (204) extends axially therefrom in better visual comformity with typical syringes. The abraded surfaces (240, 216) include radial protrusion patterns (218) and a plug extending from the plunger (202) prevents the abraded surfaces (242, 216) from meshing to thereby reduce packing of the pill particles between the abraded surfaces (216).  The plug also blocks the catheter (204) when the plunger (202) is fully advanced into the barrel to prevent the medication from escaping via the catheter (204) prior to aspiration.
